6. Evidence for Lake Turkana in Africa is the best at showing what?

  • Living fossils
  • Genetic drift
  • Punctuated evolution
  • Natural selection
  • Gradualism

7. Measuring changes in the SIZE and SHAPE of fossils is a way of monitoring what?

  • Rates of evolution
  • Gradualism
  • Natural selection
  • Genetic drift

8. What are living fossils?

  • Species that remain virtually unchanged for millions of years
  • Fossils which fully preserve the organism, including organs and hairs
  • Animals that are partially related to fossilised organisms

9. Fossil measurements must be expressed as what?

  • Logs
  • DPM
  • Equations
  • FPs

10. Who are at greater risk of extinction?

  • Specialists
  • Generalists

11. Long periods of no evolutionary change are PUNCTUATED by rapid evolution when SPECIATION occurs is the theory of what?

  • Natural selection
  • Punctuated equilibrium
  • Gradualism

12. The result of an complete fossil record - intermediates were very common

  • False
  • True

13. Most fossil records don’t reflect gradualism

  • True
  • False

14. 'Evolution of reproductive isolation' is a definition for what?

  • Gradualism
  • Microevolution
  • Speciation
  • Macroevolution

15. Punctuated evolution may occur because...

  • Small isolated populations evolve rapidly
  • All of the above
  • New species arise by splitting off from lineages
  • Sub-population gives rise to new species
  • New species originates in a very small part of ancestral range so fossils are rare

16. Does evolution appears to occur at different rates?

  • Yes
  • No

17. 'Change in gene frequencies' is the definition for what?

  • Gradualism
  • Macroevolution
  • Microevolution
  • Speciation

18. Westoll (1949) studied the evolution of what?

  • Trilobites
  • Lung fish
  • Horse teeth
  • Worms

19. Lampetra is an example of what?

  • A living fossil
  • An evolutionary change
  • Natural selection

20. 'Patterns in change of species composition over geological time periods' is a definition for what?

  • Speciation
  • Gradualism
  • Macroevolution
  • Microevolution
